Following on from the previous post, here's where we get into a little speculation.
While writing my last post, I had a moment of clarity. As I said, a reminder system for the NHS based on the costs they provide are a no-brainer. Really, you'd be mad not to implement it if such savings were there.
Have you ever worked with a can't-do guy? I have. I had one work for me once, and after a few weeks I wanted to fire him. What such people do is anything to avoid work, and then as much as they can to cover their own arse. They'll look for reasons not to do things, especially if they can create some form of organisational anarchy which makes measuring their delivery hard to prove.
I've realised is why the Doctors spend so much time involved in fakecharity and departmental work about smoking, obesity and alcohol. It's not that they're power mad fascists (although some are). It's about them diverting the blame to you, to try to accept that the ever increasing costs of the NHS aren't down to their inefficiency and lack of improvement, but because the population is doing it.
Missed appointments are part of this. I'm sure that many appointments are missed, but the NHS' figures are obviously bogus. It doesn't cost £650 for an appointment. I've been private and it costs around £150-200. And many missed appointments will simply mean that a day that's running late gets back onto schedule. What that's about is an indirect call for more money, or at least defending the money they already get.
It's designed to divert attention from the systemic problems of the NHS, to get you to think about the problem as simply being about the resources provided to them and the demands on the system, that these are the causes of the problems that we have.
